[0008] 可实现制冷剂高效循环,制冷效果好。 [0008] The refrigerant may be implemented efficiently cycle, cooling effect. 当电动车辆控制器工作产生热量时,可将毛细虹吸通道内的液态制冷剂加热气化,气化形成的气体再依次通过毛细虹吸通道的出口、 扩散室、回流管进入制冷剂室进行冷却形成液态制冷剂进入毛细虹吸通道的进口,实现制冷循环。 When the electric vehicle controller works produce heat, liquid refrigerant may be a capillary suction passage is heated vaporized vaporized gas outlet formed in turn by capillary suction passage, the diffusion chamber, the refrigerant return pipe into the cooling chamber is formed liquid refrigerant enters capillary suction inlet passage, to achieve the refrigeration cycle.

[0009]有两种力量促使制冷剂进入毛细虹吸通道内。 [0009] There are two forces causes the refrigerant entering the capillary suction passage. 一是由于液态制冷剂的液面高于位置最高的进口且低于位置最低的出口,液态制冷剂的液面压力促使液态制冷剂进入毛细虹吸通道的进口。 First, because of the level of liquid refrigerant is higher than the highest position and lower than the minimum import export position, the liquid pressure of the liquid refrigerant liquid refrigerant led into the inlet capillary suction channel. 二是毛细作用力。 Second, the capillary force. 当含有细微缝隙的物体与液体接触时,在浸润情况下液体沿缝隙上升或渗入,在不浸润情况下液体沿缝隙下降的现象叫毛细现象。 When an object with a liquid containing fine slit contact, increase in the infiltration or penetration of the liquid in the gap, without the infiltration of liquid along the slot drop phenomenon called capillary phenomenon. 在浸润情况下,缝隙越细,液体上升越高。 In the infiltration, the finer the gap, the higher the rising liquid. 就是指液体在细管状物体的内侧因为内聚力以及附着力的差异,克服地心引力而向上升。 It refers to the liquid inside the thin tubular objects because of differences in adhesion and cohesion, and to overcome the increased gravity. 设有防紊流罩,可以防止气流紊流,提高散热效果。 With anti-turbulence shield, airflow turbulence can be prevented, to improve the heat dissipation effect. 设有扩散室,既可以起到连通各毛细虹吸通道的出口,又可以为毛细虹吸通道内的制冷剂气化提供一释放空间,便于回流管回流,提高制冷剂的循环速度。 Has a diffusion chamber, the outlet may be played for each communication channel capillary suction, and can provide a space for the release of vaporized refrigerant in the capillary suction passage, a reflux tube was refluxed facilitate and improve the speed of circulation of the refrigerant. 本发明毛细虹吸通道类也似于热管。 The present invention is a capillary channel class may also wish to wick heat pipe. 热管是一种具有极高导热性能的传热元件,1964年发明于美国洛斯-阿洛莫斯国家实验室(Los Alamos National Laboratory)并在上世纪60年代末达到理论研宄高峰于70年代开始在工业领域大量应用。 Heat pipe is a heat transfer element having a high thermal conductivity, invented in the United States in 1964 Los - Alor Alamos National Laboratory (Los Alamos National Laboratory) and reached in the late 1960s theoretical study based on peak began in the 1970s large number of applications in the industrial field. 它通过在全封闭真空管内工质的汽、液相变来传递热量,具有极高的导热性,高达纯铜导热能力的上百倍,有“热超导体”之美称。 It is transmitted through the working fluid within the closed vacuum vapor, liquid phase change heat, with a high thermal conductivity, high thermal conductivity copper hundred times, with a "hot superconductors" reputation. 工艺过关、设计出色的热管CPU散热器,将具有普通无热管风冷散热器无法达到的强劲性能。 Clearance process, well-designed heat pipe CPU heat sink, will have no ordinary air-cooled radiator heat pipe can not be achieved strong performance. 热管问世以来,使电力电子装置的散热系统有了新的发展。 Since the advent of the heat pipe, the cooling system of power electronic devices with new development. 无论何种散热方式,其最终散热媒介是空气,其他都是中间环接。 Regardless of the cooling method, the cooling medium is air that eventually, the intermediate ring is connected to the other. 空气自然对流冷却是最直接和简便的方式,热管使自冷的应用范围迅速扩大。 Natural air convection cooling is the most direct and convenient way, the heat from the cooling tube so that the application of rapid expansion. 因为热管自冷散热系统无需风扇、没有噪音、免维修、安全可靠,热管风冷甚至自冷可以取代水冷系统, 节约水资源和相关的辅助设备投资。 Because the self-cooling heat pipe cooling system without fans, no noise, maintenance-free, safe and reliable, even self-cooled air-cooled heat pipe cooling system can be replaced, saving water resources and related auxiliary equipment investment. 此外,热管散热还能将发热件集中,甚至密封,而将散热部分移到外部或远处,能防尘、防潮、防爆,提高电器设备的安全可靠性和应用范围。 Further, the heat pipe heat dissipation member also focus, and even sealing, and the radiating portion to move away or outside, against dust, moisture, explosion, improve safety and reliability of the electrical equipment and application.

[0046]本实施例可实现制冷剂高效循环,制冷效果好。 [0046] The present embodiment can achieve efficient circulation of the refrigerant, cooling effect. 当电动车辆控制器工作产生热量时,可将毛细虹吸通道内的液态制冷剂加热气化,气化形成的气体再依次通过毛细虹吸通道的出口、扩散室、回流管进入制冷剂室进行冷却形成液态制冷剂进入毛细虹吸通道的进口,实现制冷循环。 When the electric vehicle controller works produce heat, liquid refrigerant may be a capillary suction passage is heated vaporized vaporized gas outlet formed in turn by capillary suction passage, the diffusion chamber, the refrigerant return pipe into the cooling chamber is formed liquid refrigerant enters capillary suction inlet passage, to achieve the refrigeration cycle.

[0047]有两种力量促使制冷剂进入毛细虹吸通道内。 [0047] There are two forces causes the refrigerant entering the capillary suction passage. 一是由于液态制冷剂的液面高于位置最高的进口且低于位置最低的出口,液态制冷剂的液面压力促使液态制冷剂进入毛细虹吸通道的进口。 First, because of the level of liquid refrigerant is higher than the highest position and lower than the minimum import export position, the liquid pressure of the liquid refrigerant liquid refrigerant led into the inlet capillary suction channel. 二是毛细作用力。 Second, the capillary force. 当含有细微缝隙的物体与液体接触时,在浸润情况下液体沿缝隙上升或渗入,在不浸润情况下液体沿缝隙下降的现象叫毛细现象。 When an object with a liquid containing fine slit contact, increase in the infiltration or penetration of the liquid in the gap, without the infiltration of liquid along the slot drop phenomenon called capillary phenomenon. 在浸润情况下,缝隙越细,液体上升越高。 In the infiltration, the finer the gap, the higher the rising liquid. 就是指液体在细管状物体的内侧因为内聚力以及附着力的差异,克服地心引力而向上升。 It refers to the liquid inside the thin tubular objects because of differences in adhesion and cohesion, and to overcome the increased gravity. 设有防紊流罩,可以防止气流紊流,提高散热效果。 With anti-turbulence shield, airflow turbulence can be prevented, to improve the heat dissipation effect. 设有扩散室,既可以起到连通各毛细虹吸通道的出口,又可以为毛细虹吸通道内的制冷剂气化提供一释放空间,便于回流管回流,提高制冷剂的循环速度。 Has a diffusion chamber, the outlet may be played for each communication channel capillary suction, and can provide a space for the release of vaporized refrigerant in the capillary suction passage, a reflux tube was refluxed facilitate and improve the speed of circulation of the refrigerant.

[0048]另外,本实施例毛细虹吸通道类似于热管。 [0048] Further, embodiments of the present embodiment is similar to capillary suction passage of the heat pipe. 热管是一种具有极高导热性能的传热兀件,1964年发明于美国洛斯-阿洛吴斯国家实验室Los Alamos National Laboratory并在上世纪60年代末达到理论研究高峰于70年代开始在工业领域大量应用。 A heat pipe is a kind of high thermal conductivity of the heat transfer member of Wu, was invented in the United States in 1964, Los - Alois Wu Siguo laboratories Los Alamos National Laboratory and reached a peak theoretical research in the late 1960s to the 1970s in the industry a large number of application areas. 它通过在全封闭真空管内工质的汽、液相变来传递热量,具有极高的导热性,高达纯铜导热能力的上百倍, 有“热超导体”之美称。 It is transmitted through the working fluid within the closed vacuum vapor, liquid phase change heat, with a high thermal conductivity, high thermal conductivity copper hundred times, with a "hot superconductors" reputation. 工艺过关、设计出色的热管CPU散热器,将具有普通无热管风冷散热器无法达到的强劲性能。 Clearance process, well-designed heat pipe CPU heat sink, will have no ordinary air-cooled radiator heat pipe can not be achieved strong performance. 热管问世以来,使电力电子装置的散热系统有了新的发展。 Since the advent of the heat pipe, the cooling system of power electronic devices with new development. 无论何种散热方式,其最终散热媒介是空气,其他都是中间环接。 Regardless of the cooling method, the cooling medium is air that eventually, the intermediate ring is connected to the other. 空气自然对流冷却是最直接和简便的方式,热管使自冷的应用范围迅速扩大。 Natural air convection cooling is the most direct and convenient way, the heat from the cooling tube so that the application of rapid expansion. 因为热管自冷散热系统无需风扇、没有噪音、 免维修、安全可靠,热管风冷甚至自冷可以取代水冷系统,节约水资源和相关的辅助设备投资。 Because the self-cooling heat pipe cooling system without fans, no noise, maintenance-free, safe and reliable, even self-cooled air-cooled heat pipe cooling system can be replaced, saving water resources and related auxiliary equipment investment. 此外,热管散热还能将发热件集中,甚至密封,而将散热部分移到外部或远处,能防尘、 防潮、防爆,提高电器设备的安全可靠性和应用范围。 Further, the heat pipe heat dissipation member also focus, and even sealing, and the radiating portion to move away or outside, against dust, moisture, explosion, improve safety and reliability of the electrical equipment and application.
